CAR-HEATER.

SPECIFICATION forming part of Letters Patent No. 743,726, dated November10, 1903.

implication illed November 3, 1902, Serial No. 129,820. (No model)l Toall whom, it may concern:

Be it known that I, XVILLIAM A. JOSEPH, a citizen of the UnitedStates,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Oar-Heaters, of whichthe following is a full, clear, and exact specifica'- tion.

My invention relates more particularly to that class of car-heaters inwhich the car is heated by water circulating 'through a suitableradiating-coil, which is heated by one or more drums per car, suppliedwith steam from a pipe common to all of said drums and usuallydesignated as a train-pipe gl and my invention has for one of itsimportant objects to provide means whereby the hot-water coil maybe'heated by means of said drums at one or more points on each car, asdesired, so that when conditions require the car may be heated at oneend or in one locality independently of the other end or otherlocalities or by using one or less than the entire number ofthe drums oneach car the temperature of the car may be regulated as desired.

A further object of my invention is to provide means whereby the steamfrom the trainpipe may pass through one or more of the drums on eachcarin exclusion of the others.

A further object of my invention is to provide improved means wherebythe steam which passes into any oneoi the drumsfor heating the hot-watercoil or pipe passes on again into the train-pipe and is thus utilizedfor heating the next drum in the system, a still further object being toopen the drip from the drum simultaneously with the closing of the steamdischarge or outlet therefrom.

W'ith these ends in view my invention consists in certain features ofnovelty in the construction, combination, and'arrangement of parts bywhich the said objects and certain other objects hereinafter appearingare attained, all as fully described with reference to the accompanyingdrawings, and more particularly pointed out in the claims.

In the said drawings, Figure 1 is a perspective view of my improvedcar-heating system, showing its relation to the loor of a car, which isindicated in dotted lines; and Fig. 2 is an enlarged verticallongitudinal sectional view of one ot the drums and connected parts.

1 2 are the hot-water coils or radiators arranged along opposite sidesof the car and constituting continuations of the same hotwater pipe,which is connected thereto in the usual or any suitable way. One end ofthis pipe usually connects with an expansiondrum 4 and the other endwith a stove-heater 5, usually employed in connection with systems of4this character, and from this heater 5 the pipe 3 extends to theexpansion-drum 4, as usual, all of these parts being of the ordinary'andwell-known construction and of any other suitable form and arrangement.

G78' are the steam-drums, three of which are employed on each car in theexample of my invention illustrated in the drawings and each of whichsurrounds the pipe 3 throughout a sufficient portion of its length toinsure the heating of the water in the pipe 3, as heretofore. lThe drum6, which is nearest the heater 5, is provided with a steam-inlet pipe 9,which is connected by pipe 10 to an antipounder 11, which in turn isconnected to the train-pipe 12 bya short connection 13, which isgoverned by stop-cock 111 inthe usual or any suitableway, so as tosupply steam to the drum 6 for heatin g the portion of the pipe 3inclosed thereby. `The opposite end of the drum 6 and, in fact, thecorresponding end of each of the other drums is provided with asteam-outlet port 15, which leads into a valve-housing 16, with which isconnected a steam-outlet pipe 17, and between the pipe 17 and the port15 is interposed a valve-'seat 1S, which maybe closed by adownwardlyopening valve 19 on a threaded valve-stein 20, whose handles21, if desired, may be eX- tended upwardly through the floor of the car,so as to be accessible for operation from the inside. This valve-stem 2Ois also provided with an extension 22, which passes through a suitableguide 23 and carries a valve 24, closing a drip 25, communicating withthe bottom of drum 6 tliroughaport 26, the valve 24: being adownwardly-closing valve,while the valve 19 is an upwardly-closingvalve, and consequently when the latter is open for permitting the steamto pass from the drum into the outletfpipe 17 the valve 24 will besimultaneously Closed, and vice versa. The extension 22 of the stem ispreferably made of considerable length and composed of copper or someother material capable of rapid vexpansion and contraction under changeof temperature, so that, if desired, the valve 24 may be allowed toremain slightly away from its seat when the valve 19 is entirely open,but will subsequently ind its seat and close as the heat of the steamcauses the extension 22 to expand.

It will of course be understood that the construction of double valve 1924 with the ports 15 26 and double-valve seats are provided at theoutlet end of cach of the drums; but while the steam-inlet to the firstdrum 6 is controlled by the stop-cock 14 the inlet ends of the otherdrums 7 S are controlled by independent stop-cocks 27 2S, respectively,having suitable handles 29 30, which may be extended through the floorof the car, so as to be capable of operation from the inside.

At a point in the train-pipe 12, between the stop-cock 14 and thesourceof supply, which is at the left-hand end of the system, as illustratedin the accompanying drawings, the train-pipe is connected to a branch3l, which leads past the drum 6 to a T 32, or other suitable fitting,which connects it with steamoutlet pipe 17 of the drum G, and thence toa crossover branch or pipe 33 to a T 34 or other suitable iitting, whichconnects the train-pipe to the inlet stop-cock 27 of the drum 7 and alsoto a branch 35, which continues past the drum 7 and connects with a T 36or'other suitable fitting, which places branch 35 in communication withthe outletpipe 17 of drum 7 and also in communication with a crossoverpipe or branch 37, which connects with a T 38 or other suitable fitting,for establishing communication between pipe 37 and inlet-cock 28 of thedrum 3 and also with a pipe 39, which extends past drums to the afterend thereof, where it is connected with outlet-pipe 17 of drum 8 by aT40 or other suitable iitting, which is also connected with the maintrain-pipe 12, leading from the discharge end of the system. The variousbranches 31, 33, 35, 37, and 39, however, are merely continuations of asingle train-pipe deected from side to side of the car to connect withthe different drums.

With the system thus constructed it will be seen that any one of thedrums may be utilized in exclusion of the others, for when the valve 19is closed against its seat 18 the steam can no longer circulate throughthe drums 6, 7, or S; but the train-pipe, nevertheless, is notobstructed by the closing of the valve 19,

and consequently any one of the drums beyond the valve 19 which isclosed may receive the full supply of steam. The drums 7 and 8 are eachprovided with the independent inlet-valves 29 and 30,as beforeexplained, and While the drum 6 is not shown as provided with anindependent inlet-valve in its inlet 9 the steam may, nevertheless, beentirely shut ofl from said inlet 9 by means of the stop cock 14, whichprevents the steam from passing into the antipounder, whence it passesinto the inlet 9 through the branch 10.

Having thus described my invention, what I claim as new therein, anddesire to secure by Letters Patent, is*

1. In a car-heating system, the combination of a train steam-pipe, acontinuous water-circulatory pipe, a plurality of steam-drumssurrounding said water-pipe at intervalsthroughout its length on eachcar and each having a drain leading directly from the lower side of oneend and direct connection at both ends with said train steam-pipe,valves arranged in close proximity to the ends of said drums forcontrolling the said steam connection with the train-pipe at one end ofeach, and double valves arranged contiguous to the other ends of saiddrums for controlling the said drain and steam connection with thetrain-pipe at the other end vof each.

, 2. In a car-heating system, the combination of a train steam-pipe, acontinuous water-circulatory pipe, a plurality of steam-d rumssurrounding said water-pipe at in tervals throughout its length on eachcar and each having a drain leading directly from the lower side of oneend and direct connection at both ends with said train steam-pipe,valves arranged in close proximity to the ends of said drums forcontrolling said steam connection with the train-pipe at one end ofeach, double valves arranged contiguous to the other ends of said drumsfor controlling the said drain and steampipe connection at the other endof each, an additional steam-drum surrounding said water-pipe at anotherpoint and having a drain and a direct connection with said steam-pipe atone end, a double valve controlling the last said drain and directconnection, an antipounder, a pipe connecting said antipounder with theother end of said additional drum,and a valve interposed in thetrain-pipe between the source of steam-supply and said antipounder.
